Starting relay

The utility model discloses a starting relay comprising a housing, in which is disposed a pressing plate. A top cover is disposed on the housing, and is disposed above the pressing plate. An O-shaped sealing ring and a plastic ring, which are in an up-down arrangement, are disposed among the housing, the top cover, and the pressing plate. The starting relay also comprises a reset spring used for driving a contact to reset and a binding post used for wiring. The starting relay is characterized in that the O-shaped sealing ring can be extruded to be deformed by a three-surface structure formed by the inclined surface of the externally-inclined top surface of the plastic ring, the inner wall of the housing, and the end surface of the top end, and therefore the sealing structure of the inner side of the relay can be formed. The starting relay is advantageous in that 1, the sealing performance is good, and the water cannot enter the inner side of the relay; 2, the design of the reset spring is more reasonable, the anti-shock effect of the contact of the starting relay is good, and the anti-shock performance of the whole starting relay can be improved; 3, the connection between the binding post and the starting relay can be changed from the single-point connection to the double-point connection, and therefore the structure is firm, and the strength is high.
